Change inserted value on trigger

Hi guys,

Here is a section of my trigger...

INSERT INTO XYZ (SupplierCode, ActiveStatus, DateUpdated, UpdatedBy)
    SELECT
         i.Supplier, i.UserField2,CURRENT_TIMESTAMP, SYSTEM_USER
    FROM
         inserted as i LEFT OUTER JOIN [TriggerTablesAscent].[dbo].[SupplierStatus] tta ON i.Supplier = tta.SupplierCode

Open in new window


My ActiveStatus field is stored as bit. I have just noticed the UserField2 is a single char of Y or N. I need to convert Y into True and N into False before the insert.

How is it best to achieve this?

Thanks,
Dean.

Use a CASE expression like CASE I.UserField2 WHEN = 'Y' THEN 1 WHEN 'N' THEN 0 END or IIF() when your on SQL Server 2012+.

Would the case statement sit above INSERT INTO?

No, it would be inline.

If you want True and False, then...

INSERT INTO XYZ (SupplierCode, ActiveStatus, DateUpdated, UpdatedBy)
    SELECT
         i.Supplier,CASE I.UserField2 WHEN 'Y' THEN 'True' ELSE 'False' END,CURRENT_TIMESTAMP, SYSTEM_USER
    FROM
         inserted as i LEFT OUTER JOIN [TriggerTablesAscent].[dbo].[SupplierStatus] tta ON i.Supplier = tta.SupplierCode

Open in new window


If you want 1 or 0 then...

INSERT INTO XYZ (SupplierCode, ActiveStatus, DateUpdated, UpdatedBy)
    SELECT
         i.Supplier,CASE I.UserField2 WHEN 'Y' THEN 1 ELSE 0 END,CURRENT_TIMESTAMP, SYSTEM_USER
    FROM
         inserted as i LEFT OUTER JOIN [TriggerTablesAscent].[dbo].[SupplierStatus] tta ON i.Supplier = tta.SupplierCode

Open in new window


If you're going to get technical about it, then true should be -1 and false should be 0 (or not true, or everything else). What specific data types do you want? An integer or a string?

Nope. Read the link and my post again. CASE is an expression not a statement.

Thanks for the feedback. Lee that worked for the case above, but should it also work for an update? My Insert works but my update fails:

  SET
        ActiveStatus = CASE i.UserField2 WHEN 'Y' THEN 'True' ELSE 'False' END,CURRENT_TIMESTAMP, SYSTEM_USER, DateUpdated = CURRENT_TIMESTAMP, UpdatedBy = SYSTEM_USER

Open in new window


The True or False is going into a bit field.

Thanks,
Dean

Then use 1 and 0 as true and false.
